Factorial and permutation
WebThe PERMUTATION FORMULA The number of permutations of n objects taken r at a time:! P(n,r)= n! (n"r)! This formula is used when a counting problem involves both: 1. Choosing … WebThe permutations of 4 numbers taken from 10 numbers equal to the factorial of 10 divided by the factorial of the difference of 10 and 4. The permutations is easily calculated using \(^nP_r = \frac{n!}{(n - r)!}\).
